Abstract

Moving image reception quality evaluator 4 for evaluating the reception quality of a moving image receiver 31 of the user, moving image reception quality evaluator 5 for evaluating the reception quality of a moving image receiver 32 for receiving the same moving image as the moving image receiver 31, and a determination machine 1 for determining the reception quality of the moving image receiver 31 based on comparison between the evaluation value of the moving image reception quality evaluator 4 and the evaluation value of the moving image reception quality evaluator 5 are provided. A quality provider for managing the moving image reception quality evaluator 4, the moving image reception quality evaluator 5, and the determination machine 1 pays the amount determined based on the reception quality determined by the determination machine 1 to a service provider for providing moving image communication service.

Claims

1. A moving image reception quality determination apparatus comprising:

a moving image transmitter for transmitting a moving image;

a first moving image receiver for receiving the moving image transmitted by said moving image transmitter through a network;

a first moving image reception quality evaluator for evaluating reception quality of the moving image of said first moving image receiver;

a second moving image receiver for receiving the moving image transmitted by said moving image transmitter through said network;

a second moving image reception quality evaluator for evaluating reception quality of the moving image of said second moving image receiver; and

a determination machine for determining the reception quality of the moving image of said first moving image receiver based on comparison between a first evaluation value output by said first moving image reception quality evaluator and a second evaluation value output by said second moving image reception quality evaluator.

2. The moving image reception quality determination apparatus as claimed in

claim 1

wherein said determination machine determines the reception quality based on a quality degradation index, a value of summing up differences between the first and second evaluation values over a specific time period.

3. The moving image reception quality determination apparatus as claimed in

claim 1

, wherein a service provider for providing moving image communication service between said moving image transmitter and said first moving image receiver contracts with a user using said first moving image receiver to receive a moving image for returning a part of service charge to the user based on the first evaluation value;

and

wherein contracts with a quality provider for managing said first moving image reception quality evaluator, said second moving image reception quality evaluator, and said determination machine for the quality provider to pay an amount determined based on the reception quality determined by said determination machine to the service provider.
